Were all jonesing for Spirit Guard Udyr, but as you know patch 3.9 has been a little choppy. Were still working hard to stomp out bugs and make sure the games running at full speed for the weekend, so we arent comfortable diverting resources to hotfix SGU at this time.
The unhappy side effect of this is that were stringing you along on the Udyr hype train, and that feels crappy. Sorry. Its really not the intent as indicated by a variety of previous posts, we were hoping to get SGU out a bit earlier. Were currently looking at early next week, and well keep you posted.
Hope you can understand that were prioritizing the overall game experience before we ship new content, even though we know that sucks for those of you that are eagerly awaiting SGU!
